4 Page. GENERAL This document describes the Anybus DeviceNet features supported by the SE-330/SE-330AU/SE-330HV. The DeviceNet module supports Explicit, Polled I/O, Bit-Strobe, and Change-of-State messages of predefined master/slave connection set. It does not support the Unconnected Message Manager (UCMM). 2.

Three eds files provide support for the standard SE-330, SE-330AU, and the SE-330HV. The eds file includes configuration information for I/O assemblies. The I/O assembly associated with each type of connection object can be selected by the configuration tool. These I/O assemblies are accessed using a DeviceNet master such as an A-B scanner module, see Section 3.5. I/O configuration parameters are stored in non-volatile memory. Not all attributes listed in this document are defined by the eds file. Most attributes are part of the DeviceNet protocol, and do not need to be adjusted. 3. DEVICENET OBJECTS (In Order of Class Number) The module supports the following objects: TABLE 3.

These attributes must be set prior to the corresponding connection being established. The Anybus module supports six INPUT and OUTPUT assemblies, however only three INPUT assemblies and one OUTPUT assembly are supported. The INPUT or OUTPUT assembly is selected using a configuration tool and the corresponding parameter value is sent to the module. Parameters are stored in non-volatile memory and are retained on loss of control power. INPUT and OUTPUT assemblies are described in Section 3.4.

Output : Commands Assembly Class 4, Instance 50, Attribute 3 Byte size = Parameter value 0 is Output Output is the default for Polled and Strobed Consumption Output 2, Output 3, Output 4, Output 5, Output 6: Not supported by SE-330/SE-330AU/SE-330HV RSNETWORX I/O CONFIGURATION The DeviceNet interface module supports Polling, Bit Strobe, and Change of State. The Polling connection is the default. The I/O tab in RSNetWorx lists the configuration options with the default in bold. Each connection type has an associated INPUT and OUTPUT assembly. The I/O tab shows the default assembly for each connection type. The INPUT assembly type for a specific connection can be changed using parameters, 3, and 5. The OUTPUT assembly (parameter 2 and 4) cannot be changed and is fixed as OUTPUT with a byte size of. When the INPUT assembly for a specific connection is changed to a value other than the default, the scanner may indicate a configuration warning. Disregard the warning. Use Edit I/O Parameters to enable the required connection and adjust the byte size to match the INPUT assembly. The byte size for the OUTPUT must be set to. NOTE: The Anybus module supports six I/O assemblies and requires the EDS file to support six setting values, even though the SE-330/SE-330AU/SE-330HV does not support all six I/O assemblies.
